Raw (AP) and purified single-walled carbon nanotubes (SWNTs) were utilized for the preparation of SWNT-epoxy composites. Purified functionalized SWNTs provide a significantly greater enhancement of the thermal conductivity, whereas AP-SWNTs allow the best electrical properties because of their ability to form efficient percolating network. A series of SWNT samples of varying purity but identical chemical functionality were prepared to delineate the effect of SWNT purity on the thermal conductivity of SWNT-epoxy composites. We found that purified SWNTs provide ~5 times greater enhancement of the thermal conductivity than the impure SWNT fraction demonstrating the significance of SWNTs quality for thermal management.
